Abstract
An apparatus for displaying characters on a picture screen of a display unit has an image point memory interconnected between an image generator and a display unit. The image generator controls the display of the characters on a picture screen of the display unit and contains a character generator in which data words corresponding to the shape of the characters to be displayed are stored. The image point memory serves as an image repetition memory and contains an allocated memory having memory elements corresponding to all of the possible raster points on the picture screen. The contents of the allocated memory are cyclically read out and transmitted as a video signal to the display unit wherein the characters are displayed line by line. A logic element is preconnected to the allocated memory for permitting a number of characters to be superimposed for generating multiple characters and further permitting certain characters to be cancelled.
